An aerodynamic device is arranged for mounting to a vehicle or a trailer for reducing its wind resistance. The aerodynamic device includes at least one sheet material arranged to be mounted to the vehicle/trailer and associated with a corresponding wall portion of the vehicle/trailer. Each wall portion has an outer surface and an inner surface and extends towards the rear of the vehicle/trailer. In a deployed first state, each sheet material is arranged to at least partly extend beyond a rearmost position of the wall portion. In a stored second state, each sheet material is arranged to be inserted such that is faces towards the inner surface. A vehicle or a trailer including the aerodynamic device is also provided.

An aerodynamic device arranged for mounting to a vehicle or a trailer for reducing the wind resistance of the vehicle/trailer comprising a cargo space, the aerodynamic device comprising at least one sheet material, each sheet material being arranged to be mounted to the vehicle/trailer such that each sheet material is associated with a corresponding wall portion of the vehicle/trailer, each wall portion having an outer surface and an inner surface, the inner surface facing the cargo space, the wall portion furthermore extending towards the rear of the vehicle/trailer, where, in a deployed first state, each sheet material is arranged to at least partly extend beyond a rearmost position of the wall portion, wherein in a stored second state, each sheet material is arranged to be inserted such that it faces towards the inner surface, the at least one sheet material comprising a first sheet material and a second sheet material, each sheet material being arranged to be mounted to the vehicle/trailer such that the first sheet material is associated with a first wall portion of the vehicle/trailer, and the second sheet material is associated with a second wall portion of the vehicle/trailer, the wall portions being mutually parallel, the outer surfaces facing, away from each other and the inner surfaces facing towards each other,each sheet material comprising a first sub-sheet and a second sub-sheet, where the first sub-sheet sheet is closer to the corresponding wall portion than the second sub-sheet, and where the first sub-sheet and the second sub-sheet are connected to each other at a rearmost edge, where furthermore the first sub-sheet is arranged to travel a longer distance than the second sub-sheet when the sheet material is moved from the stored second state to the deployed first state. 2. An aerodynamic device according to claim 1, wherein the first sheet material comprises an outer edge, an inner edge an upper edge and a lower edge, and that the second sheet material comprises an outer edge, an inner edge, an upper edge and a lower edge, the edges constituting borders of the sheet materials, where, in the deployed first state, the outer edges are closer to each other than the inner edges. 3. An aerodynamic device according to claim 1, wherein the aerodynamic device comprises an upper sheet material, the upper sheet material being arranged to be mounted to the vehicle/trailer such that it is associated with an upper wall portion which constitutes a roof. 4. An aerodynamic device according to claim 3, wherein the upper sheet material comprises an outer edge an inner edge, a first side edge and a second side edge, the edges constituting borders of the upper sheet material. 5. An aerodynamic device according to claim 1, wherein each sheet material is of a main triangular shape, comprising an inner edge, a first outer edge and a second outer edge, wherein the rearmost edge is an apex of the triangle. 6. An aerodynamic device according to claim 1, wherein each sheet material is provided with rigid structures which make each flexible sheet material form a desired shape when it is in its deployed state. 7. An aerodynamic device according to claim 1, wherein the sheet material in the deployed first state follows a curved shape, constituting a mainly continuous extension of the corresponding wall portion. 8. An aerodynamic device according to claim 1, wherein each sheet material is arranged to be inserted between the corresponding wall portion and a corresponding inner wall portion.
